9. Kari and Susie are playing a game with three colored markers- green, red and blue. On her next turn, if Susie chooses a marker at random and it is green, she wins the game. What are the outcomes that could happen? green, red, blue What is the probability of choosing a green marker? 1/3, 0.3, 33 1/3%
10. Nicole found out that Jessica was born in May. What is the probability that she can guess the correct date of Jessicaâs birthday on the first try? How many outcomes are possible? 31 days in May What is the probability of the event? 1/31
11. More Probability and other stuff If you roll one die what is the probability that the number that shows is greater than 4? If I roll one die the probability that the number that shows is greater than 4 is 2/6 which simplifies to 1/3. The possibilities would be 1, 2, 3, 4, 5, 6. The only two numbers greater than 4 would be 5 and 6.
12. I have 3 pennies and 5 dimes in my pocket. If I pull out one coin what is the probability that I get a dime? The probability that I get a dime is 5 chances out of eight. 5/8, 0.625, 62.5%

14. EXAMPLE 2 Finding Experimental Probability You roll a number cube 100 times. Your results are given in the table below. Find the experimental probability of rolling a 6 . = 0.18 = 18% P (rolling a 6 ) = 18 100 Number of favorable outcomes Total number of rolls The experimental probability of rolling a 6 is 18% or 9/50 . ANSWER
15. EXAMPLE 2 Finding Experimental Probability You roll a number cube 100 times. Your results are given in the table below. Find the experimental probability of rolling a 1 or 2 . = 0.32 = 32% 17+15= 32 P (rolling a 1 or 2 ) = 32 100 Number of favorable outcomes Total number of rolls The experimental probability of rolling a 1 or 2 is 32% or 8/25 .
